What is DNA?

DNA (deoxyribonucleic acid) is a nucleic acid that contains genetic instructions used by nearly all known life. Nearly every cell contains DNA. The mitochondria also contain mitochondrial DNA.

Structurally DNA consists of two long coils of complementary bases (commonly: A, T, G, C), these are covalently linked with sugars and phosphate to create a polynucleotide chain. The sugar and phosphate form the backbone while the complementary bases link by hydrogen bonds holding the two chains together.

When you look at a diagram of DNA often each strand will have an arrow, this is to illustrate that each strand has chemical polarity. This is also denoted by one end (3’ hydroxyl) is the 3’ end, it has an unlinked – OH group which is on the 3’ position on the sugar while at the other end (5’ phosphate) is the 5’ end which has an unlinked phosphate group at the 5’ position on the other sugar ring.

The structure of DNA is commonly referred to as a double helix which looks like a twisted ladder. The sequence of the bases determines the genetic code. In eukaryotic cells, DNA can be found in the nucleus. In prokaryotic cells, DNA can be found free-floating in the cytoplasm.
